Something is fundamentally broken in Vista's network stack IMHO. Was the server Linux based ? The readahead module improved the Vista problem on Linux according to my tests, but one of our OEM's made some kernel changes to their version of Linux to help the problem more.

Jeremy, Andrew I think from the context that Andrew has already tried that - at work we have decided that Vista simply isn't worth the hassle now. We can't even manage to get Vista on a new laptop to get an IP address from DHCP, never mind connect to our Samba DC! Everything else can get an IP (3com and Cisco switches, Mitel IP phones, XP, Solaris, *BSD, etc). Something is fundamentally broken in Vista's network stack IMHO.

Ah - the readahead issue. Try using 3.0.25 with the vfs readahead module.

[Samba] Nagging performance issues with Vista
Hi All, I've got some performance issues with Samba and Vista that I just can't seem to figure out. Googling and fiddling has all been in vain up until now, so I'm not sure what I can do other than wait for Samba 4, but maybe someone here can find something I've missed. First off, the server is an Athlon 64 1.8GHz running Gentoo 2006.1, tested with both Samba 3.0.24 and 3.0.25a. Gigabit network is handled by the onboard nForce controller, and it's got a software RAID 5 setup that has been running fine for months. The client is a dual core Windows box with a PCI-Express gigabit card. Netperf pegs the network at 100Mbytes/sec, so there's no problems there. Transfers via FTP on both Windows XP and Vista work out around about 55Mbytes/sec consistently, and SMB transfers under Windows XP also top out around 50-55Mbytes/sec, which seems to be the limit of the I/O on the client. Vista however, no matter what I do, will not read from Samba shares at any more than around 5Mb/s when copying with Explorer. I timed a few different file copies between XP and Vista, and it's consistently ten times slower every time. Write speeds seem a lot better (20-30Mb/s). This happens with both Samba 3.0.24 and 3.0.25a. I've tried with the VFS readahead both on and off. I've tried with NetBIOS over TCP/IP both on and off. It's worth noting that if I use the copy command via the command prompt, read speeds jump to around 8-9Mb/s, but it's still pretty poor. Kernel version is 2.6.19 with the Gentoo patches. Samba 3.0.24 came from Gentoo Portage, while 3.0.25a was compiled directly from sources. Here's my smb.conf: [global] workgroup = PC netbios name = safari server string = Samba %v log file = /var/log/samba/log.%m max log size = 500 log level = 0 hosts allow = 192.168. 127. guest account = smbguest security = user map to guest = Bad User [store01] path = /mnt/store01 browseable = yes writable = yes guest ok = yes guest only = no create mask = 0755 vfs objects = readahead [store02] path = /mnt/store02 browseable = yes writable = yes guest ok = yes guest only = no create mask = 0755 vfs objects = readahead [store03] path = /mnt/store03 comment = store03 browseable = yes writable = yes guest ok = yes guest only = no create mask = 0755 vfs objects = readahead [Incoming] path = /mnt/store01/Incoming comment = Incoming browseable = yes writable = yes guest ok = yes guest only = no create mask = 777 vfs objects = readahead Samba logs show a few errors, I'm not sure that they're relevant, and aren't very frequent (maybe about a dozen of these lines a day), but here they are anyway: [2007/06/22 10:47:05, 0] lib/util_sock.c:read_data(534) read_data: read failure for 4 bytes to client 192.168.0.2.
